Yesterday someone stole my bike seat along with the seat post. I am planning to buy a new seat with post that fits it. My bike is a Bulls Pulsar mountain bike. I have found a seat on Amazon but I have not found a seat post that would fit this seat. I request for your help. Thanks.

You need a "seat post" which has to be exactly the same diameter as the old one.

The specs page only says "Seat post: STYX aluminum" which is not enough information.

Your best option would be to close the clamp to its normal position, and measure the internal diameter of the frame using calipers. A ruler won't be accurate enough, because while common seatposts could be in these sizes:

25.4 mm

26.2 mm

26.8 mm

27.2 mm

28.6 mm

31.2 mm etc

It is not impossible for the seatpost to be some weird in-between size.

The overall length of the seatpost is less important, only that it is long-enough.

You'll also need a seatpost with an integrated clamp at the top, or a separate clamp. Very likely whatever you buy will have a clamp included.

Separately - someone has stolen your bike seat once already. Expect that it will happen again. Some relevant links to protect your parts:
